Biased Exponent

In floating-point arithmetic, a biased exponent is the result of adding some constant (called the bias) to the exponent chosen to make the range of the exponent nonnegative.

Biased exponents are particularly useful when encoding and decoding the floating-point representations of subnormal numbers.
